GAGE FOR SEWING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 695,972, dated March25, 1902.

Application led June 3, 1901.

To @ZZ whom t may concern:

Be it known that 1, EDWARD F. TURNER, of Brocktomin the countyofPlymouth and State of Massachusetts, have invented certain new anduseful Improvements in Sewing-Machine Gages, of which the following is aspecification.

This invention relates to fair-stitch sewingmachines most commonlyemployed in applying the outer line ot' stitching around the sole edgesof McKay-sewed shoes.

It consists in a novel form of gage, substantially as hereinafterdescribed.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a vertical section through the work-plate andadjacent parts of a sewing-machine provided with my improvement, saidview also showing the work in position. Fig. 2 represents a perspectiveview of the gage removed from the other parts of the machine. Fig. 3represents a horizontal section of the work.

ln fair-stitching shoes no particular difficulty is experienced bytheoperator in properly guiding the line of stitching when this line runsin from the edge of the sole close to the upper, but on so-calledextension soles, where it is common to run the line of stitching outfrom the upper at a considerable distance close to the extension edge,the operator having nothing to guide him but his eye will frequently runoff-that is, will run the line of stitching completely olf the sole-andthus spoil or injure the Work.

In Fig. 3, 1 represents a sole in which the inner marginal portion orextension part of the sole is of moderate width only and the stitching 2runs close to the upper 3; but on the outer side of the sole thismarginal portion is much wider, as represented at 4, and the stitching 2departs quite a distance from the upper. It is on the portion 4E thatthe greatest difliculty is experienced by the operator in guiding theline of stitching, and this difculty is greater on high-speed machines,such as the ordinary chain-stitch fairstitching machines, than it is ona machine having a slower speed, such as the Goodyear machines forsewing soles on -welted shoes.

I am aware that it has been proposed to employ a gage or guide on amachine of the Goodyear typo to engage the lasted upper,

Serial No. 62,884. (No model.)

such gage being moved in and out by manually-operated mechanism, so asto vary the distance of a line of stitching from the upper, and I do notclaim such construction.

5 represents the post of the sewing-machine, the same carrying at itsupper end a Worksupporting plate 6, above which are shown the awl 7 andits bar 8 and the presser-foot 9, and below which are shown the needle10 and its bar 11, said needle cooperating with a cast-off, which is notshown. The plate G has the usual free edge 12, close to which is a hole13, through which the awl and needle operate. The work 1 is shown inposition to be operated upon in Fig. 1.

At the back of the post 5 I aiiix, by means of screws 14 14C, a block15, forming a base to which is attached a flexible arm 1G, having asubst-antially vertical portion 17, secured by screws 1S 1S to saidblock, and a substantially horizontal portion 19, overlying the plate Gand provided at its forward or outer end with a roller 20, journaled ona pin 2l. A stud 22, fixed to the upper end of the block 15 andoccupying an elongated slot 23 in the horizontal portion 19 of the arm16, aords an abutment for resisting the lateral movements of said arm.Projecting rearwardly from the block 15 is a threaded stein or spindle24, surrounded by a spring 25, bearing against the rear side of arm 16and engaged by adjustingnuts 26 2G on said spindle, whereby its tensionmay be regulated. Screwed on the spindle 24, in front of the arm 16, isa nut 27, forming an abutment or stop to limit the forward movement ofsaid arm under the influence of the spring 25.

Nhen the operator wishes to stitch in close to the upper, he forces thework inwardly or to the right in Fig. l and displaces the roller 2O andarm 16 rearwardly against the tension of the spring 25. The roller 2Orolls in continuous contact with the edge of the sole as the shoe is fedalong, and when the line of stitching is to come out away from the uppertoward the edge of the sole the operator decreases his inward pressureupon the shoe and allows the roll 20, under the influence of spring 25,to push or carry the Work outwardly. When the arm 16 abuts against thenut 27, the roll willbe carried no farther, and the operator is enabledto accurately gage the dis- IOO tion, said gage having means forpositivelyl adjusting the operative distance of the gage from thestitching mechanism between two extremes, and I accordingly claim suchorganization of parts broadly, irrespective of the particular mechanicalconstruction in which it is embodied.

I claiml. A sewing-machine comprising a Worksnpport, stitchingmechanism, a laterallyyielding gage above the Work-support adjacent tothe stitching mechanism and yieldingly impelled toward the latter, andmeans for positively adjusting the operative position of said gage withrespect to the stitching mechanism between two extremes.

2. A sewing-machine comprising a Worksupport, stitching mechanism, agage-roller above said support adjacent to the stitching mechanism, aholder for said roller free to move against spring-pressure in adirection to retract the gage-roller from the stitching mechanism, aspring device to move said holder in the opposite direction, and anadjustable stop to positively limit the movement of said holder betweentwo extremes.

In testimony whereof I have affixed my signature in presence of twowitnesses.
